In Search of "Dojin" by Hiroshi Suzuki (1980) Update 2

Well I simply answered some of my own questions from the prior post and continued developing my attempted recode of "Dojin" based on Mr. Suzuki's sketch and the descriptions provided by John Szczepaniak who interviewed a bunch of Japanese programmers for his book "The Untold History of Japanese Game Developers." Vol 1.  First I got a BASIC only version running, but it was a little pokey, so I compiled it using Greg Dionne's MCBASIC compiler.  Here's the BASIC version:

Here is the compiled version:

If you are seeing this post without reading the prior ones, Mr. Suzuki's "Dojin" is a lost program. It was inspired by one his earlier groundbreaking game programs "Shoplifting Boy" aka "Manbiki Shounen." Dojin then helped inspire the groundbreaking game "Uchuu Yusousen Nostromo," by Akira Takiguchi (Masakuni Mitsuhashi did a NEC PC-6001 port that I used for my port), which is considered a very early example of the survival horror game genre. This project was suggested to me by John Szczepaniak. His book provides the only substantive information that I am aware of about this missing game.

I plan to have my son Charlie to play test Dojin and make final suggestions for refining the speed and timing, and possibly code some slightly more musical elements than the bleeps and bloops I'm only capable of.  So there will be further updates.  Until then the current version can be downloaded from the Internet Archive (but not played.  The Archive emulator doesn't like compiled games):

Dodging?

But I have played the game a little (as you can see in the above video) and the player really has to work hard to avoid the enemies, so much that I wonder if "Dojin" is a Japanese play on words for the English word "dodging" (the title I will give it if I get word that it is not a good representation of the original).  But according to Szczepaniak it means something like "native" or "aboriginal" in Japanese. The light green objects are meant to be trees of the forest.  So the vibe is that you are some kind of colonialist (probably wearing a pith helmet) being chased by locals around their pastoral home. Not sure what the obstacle is. Either a rolling log, which is how my son and I thought of it, or a "car" of some kind (or possibly a bulldozer bringing "progress" to the local population and landscape.
